How can I use both a key and an index for the same dictionary value?

I need an array of data that has a numeric index, but also a human readable index. I need the latter because the numeric indices may change in the future, and I need the numeric indices as a part of a fixed length socket message.

My imagination suggests something like this:

ACTIONS = {
    (0, "ALIVE") : (1, 4, False),
    (2, "DEAD") : (2, 1, True)
}

>ACTIONS[0]
(1, 4, False)
>ACTIONS["DEAD"]
(2, 1, True)
